【摘要】 利用北京飞箭软件有限公司的有限元程序自动生成系统(FEPG),开发出一系列固定管板式换热器的有限元计算程序,并将其嵌入压力容器分析设计系统(VAS2.0)中。以管板不兼做法兰、与壳体圆弧过渡连接、正方形布管、无膨胀节的固定管板式换热器为例讨论了参数化有限元计算模型的建立、求解及后处理方法,并结合算例与ANSYS的计算结果进行了比较,相对误差在8%以内,可满足工程计算需要。更多还原

【Abstract】 With the Finite Element Program Generator (FEPG), a series of finite element programs for fixed tubesheet heat exchanger had been exploded, and these programs had been embedded into the analysis design system for pressure container (VAS2.0). With the example of a specific fixed tubesheet heat exchanger, the building up of the parameter models, the generation of the finite element programs and the postprocessor method are discussed. The results calculated by ANSYS and VAS2.0 shows that the relative error is less then eight percent, which can satisfy the engineering calculation demand.更多还原
